SPECIFICATION forming part of Letters Patent No. 641,059, dated January 9, 1900.

Application filed April 20, 1899.

ATo all whom, 731'; may concern.-

Be it known that I, IRA C. WIGHTMAN, of Norwich, in the county of Ohenango, in the State of New York, have invented new and useful Improvements in Acetylene-Gas Generators, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to acetylene-gas generators.

My object is to produce an improved generator vand a seal of oil or other non-freezable medium or liquid having an improved device for feeding the water to the calcium carbid; an improved carbid-holder comprising a series of pockets connected in series and consecutively filled with water, said connections being trapped, means being also provided for operating the feed-water valves, as well as the safety-valve, by the rise or fall of the gasometer.

It is constructed as follows, reference being had to the accompanying drawings, in which- Figure l is a vertical section of the generator and gasometer, partly in elevation. Fig. 2 is an enlarged vertical section of the generator. Fig. 3 is a top plan of the carbidholder. Fig. 4f is a sectional detail showing the trapped connection between the pockets.

A is a suitable casing comprising sides or walls and a tight bottom. An air and gas tight drum 2 is erected within said casing, creating a narrow sealing-chamber 3 between its walls and those of the casing, in which a suitable non-freezable liquid medium or agent, as a suitable oil, is placed. Into this .sealing-chamber and sealing medium the gasometer l is inverted and guided in its vertical movements by the guide-bars and rollers in the usual way. None of the sealing medium or gas enters the drum. Upon said casing a suitable water-tank 5 is suitably mounted, having a discharge pipe and valve 6 opening into a suitable water-tight auxiliary water-tank 7 provided with an ed uction pipe and valve 8. The stem of each of these valves is provided with an arm or lever 9, both pivoted upon a connecting-rod 10, which is suitably connected to a rod 11, secured at one end to the gasometer, whereby the fall of said gasometer will simultaneously open both valves Serial No. 713,735. (No model.)

to permit water to flow through said pipes and auxiliary tank, and its rise above a cer-l tain point will close both of said valves. This auxiliary tank 7 is normally always full of water, so that a discharge iiow will start the instant the valves are opened; also, if the valve should become leaky it cannot do any damage so long as valve 8 is tight, and if the valve 6 should be tight and the valve 8 leaky then the tendency to create a vacuum in it will substantially prevent the flow of any water therefrom. It therefore prevents accidental leakage of water to the carbid when the flow is supposed to be cut ott.

The generator B comprises a suitable casing 12, a vessel 13, inverted and sealed therein, and a carbid-holder 14 within said casing and vessel and comprising a series of pockets for separately receiving carbid (marked a, b, c, d, e, h, t, and 15,) grouped or arranged about a central tube 15, through which the water-feed pipe 16 is conducted, as well as the gas-eduction pipe 17. The water is fed into the compartment or pocket a, and when it is iilled to a fixed limit overows through a trapped pipe 18 into the pocket b, and in this manner the carbid is successively used up in several pockets. This pipe 17 conducts the gas into the chamber 19 in the gasometer, and 2O isthe pipe conducting it to the burners.

A suitable valve 21 in the pipe 18 is provided with a handle or lever 22, which normally engages with the top of the cover over the carbid-holder, so that said cover cannot be removed to permit access to said holder without swinging said lever out of the way, and this will close the valve 21 and prevent gas from escaping from the gasometer.

A pipe 23, connected to the pipe 20, is provided with a suitable levervalve 24, with which an arm 25 on the gasometer engages in such manner that the rise of the gasometer above a certain point will open said valve to permit the escape out of doors of the surplus gas until the pressure is reduced to safety. By closing the valve 25 in the pipe20 the gas is shut oft from the burners, and also if the valve Zetis then opened the gasometer can be substantially emptied.

The gas-eduction pipe 17 passes for a part of its length through a box 27, and adrip-nozzie 26 on said pipe is duly sealed therein,

IOO

whereby all of the condensation and other and pipes therein leading down nearly to the bottom of each compartment, except the one rst receiving the water and curved upward, 15';

a feed-water pipe extending upward through said tube and feeding water into the primary compartment, and a gas-eduction pipe eX- tending downward from the gas-chamber above said carbid-holder through said tube 2o and conducting it to a gasometer.

In witness whereof I have hereunto set my hand this 17th day of April, 1899.

IRA C. WIGHTMAN.
